I once worked where they ran 4 Cray 90 super computers. What amazed me even more than the computers was the amount of support equipment required to run those things. The power was run on copper I-beams and the cooling units were twice the size of the computers. IIRC they had 8 or 10" chilled water lines feeding the coolers.
The amazing thing is today they can put in a rack of linked CPUs, get more computing power, and just use some fans to blow outside air at any temp threw the rack to cool it.
